Same here, though it's not a SMP box(Pentium 4 2.53GHz with HTT enabled, but only one CPU in hw.ncpu, no "options SMP" in kernel configuration). After install the latest kernel(cvsup'ed about 5 hours ago) and reboot, a lot of "calcru: negative time of...." messages popped on the console: calcru: negative time of 3419 usec for pid 557 (sh) [... repeated 230+ times] calcru: negative time of 3419 usec for pid 557 (sh) calcru: negative time of 3449 usec for pid 7226 (sh) [... repeated 70 times] calcru: negative time of 3449 usec for pid 7226 (sh) Last known working kernel was cvsup'ed on Jun-17-2004. It turns out that the system doesn't freeze and still works(able to build mozilla firefox increamentally without crash) at this moment. > > calcru: negative time of 0 usec for pid 21261 (sh) > calcru: negative time of 0 usec for pid 21261 (sh) [...]
